STARCH-SEPA RATO R.

SPECIFICATION formingV part of Letters Patent No. 261,445, dated July18, 1882,

' Application led April 10, 1882. (Nomodehl starch stock is placed, andwhich are agitated or shaken to separate the coarser particles ofstockfrom the finer amylaeeous particles, which pass through said bottoms,and which are afterward manipulated to form starch.

The invention consists in the combination, with such aseparatorbolting-frame, of a novel combination of devices, hereinafterparticularly described and claimed, for supporting the same, so as toprovide for shaking or reciprocating it rapidly and for imparting such amotion toit.

In the accompanying drawings, Figure l represents a plan ot' a machineembodying my invention. Fig. 2 represents a side view there; of.' Fig. 3represents a transverse section ot' one side of the bolting-frame andits supportingbox, showing the devices forsupporting one end of saidbolting-frame; and Fig. 4 represents asimilar view, showing the deviceswhich support the other end of said bolting-frame.

Similar letters of reference designate corresponding parts in all thefigures. Y

A designates the stationary box or receiver of the machine, which has animperforate bottom, at one end of which may be an opening for thedischarge of the material delivered into it.

B designates the shaking-frame, which has a bottom of'bolting-cloth orother reticulated or foraminous material, and which tits above andwithin the box A, bothl it and the box A being in an inclined position,as clearly shown in Fig. 2. The stationary box A rests on and issupported by a frame-work, O, while lthe shaking-frame B is supported bythe said stationary box. One end of the bolting-frame B has a slidingsupport, while'the other end has a swinging support. The slidingsupports are formed by tracks C' on the box A and shoes or slides D onthe bolting-frame B. The tracks C are here shown as composed of angleandloose pulleys L Lu pieces, which rest upon the top edges of the sides ofthe box A and are screwed or bolted tothe outer sides thereof, asclearly seen in Fig. 4,' and the shoes orA slides D are bolted orotherwise secured to the sides of the frame C and run in grooves b inthe tracks C.

At the end of the box A opposite to that at which are the slidingsupports are upright standards or bearings E, to the upper ends ofwhich, above the box A, are pivoted links or bars F, which are adaptedto swing or vibrate on their pivots c. At the sides of the bolting-frameB are secured standards or bearings G, which project above the frame Band are connected to the upper ends of the links or bars F by pivots d.The standards or bearings E and G may he considered as parts of the boxA and frame B, respectively, and it is obvious that the links or bars Fmay swing freely back and forth to permit ot' the recprocation ot' theboltingframe B. The links or bars vF are short, and hence it will beseen that as the bolting-frame B is reciprocated it also has arising-and falling motion at one end, due to the arcs described by thepivots d, and such rising-and-falling motion renders the bolting-framemuch more effective in its operation. By this arrangement of links orbars F, I am not only enabled to make them short, but with a givenamount ot'longitudinal movement of the Screen I obtain a relativelygreat rising-andfalling movement. To enable me to make these links orbars F so short, I pivot them at their lower ends to the side walls ofthe receiver, as before stated, all of which is of considerableadvantage over those machines of a similar nature wherein long vibratoryarms are connected at their lower ends to a horizontal transverse shaftrocking in bearings secured to the bed-frame of the machine.

H designates pitmen or connecting rods connected directlyT to wrist-pinse on opposite sides ofthe bolting-frame B, and actuated by cranks I onthe ends of the shaft J, which is mounted in suitable bearings, K, andmay be rotated by a belt, for which are provided fast The shaftJ mayalso have a fly-wheel, M, for making its rotation more uniform.

In lieu of the two rods H, a single rod cong nected to thebolting-t'rame B at about the middle of its Width might be used.

The starch stock is placed in the boltingframe Il, and by itsreciprocation all the finer amylaceous particles which are to bemanipulated to makestarch arecaused to pass through the reticulated orforaniinous bottom thereof, while the coarser particles are retainedthereon and are delivered separately.

I am awarethatthebolting-frame ofastarchseparator has been suspendedabove a stationary box or receiver by upright arms connected with thebolting-franle and pivoted at their lower ends to the iioor whichsupports the boX or receiver; but such I do not claim.

VVhatI claim as my invention, and desire to secure by Letters Patent,is-

In a starch separator composed or' a stationary box or receiver, abolting-fralne, and mechanism for reciprocating the latter, theherein-described devices for supporting the bolting-frame on and abovethe box or receiver', consisting ofthe vertical standards E E, rigidlyseeured to and projecting above the side Walls ot the box or receiver,the vertical stand ards G G, rigidly secured to and projecting above theside Walls of the bolting-frame, and the short links F F, having theirlower ends pivoted to the standards on the box or receiver and theirupper ends pivoted to the standards on the bolting frame, allsubstantially as shown and described.
